If the Nazis conquered the USSR?

How can I say this without offending somebody? Hitler was human! Not only was he human but he was a leader, somehow he could collect together people that listened to him. What if he had been an idiot? Then he would have ended up being what he already was, a chest beating trade union leader. This one barking dog managed to slip the union lead, and came to power in a series of illegal but brilliant moves.

His grasp of war tactics seemed remarkably astute at first. Hit hard and fast before the sods have a chance to move. Some say this wisdom came on the advice of others but all leaders need cooperate with others to form a semblance of government. Early on he made a deal with the army and had the brownshirts liquidated; so he had to go along with the army recommendations for a while. He had an ace up his sleeve in formation of the Gestapo, they were not just into brutality but bending minds to suit their will by any means. Even the army became intimidated by their power.

One can see his continuing see-saw relationship with the generals in the way Rommel was treated, and he was no angel. At first the Generals raced across the Russia steppes taking this famous city and that famous city. Everybody in the German high command was happy until they had to admit their supply lines were over-extended and asked Hitler for more time and supplies to consolidate their victories.  

At that point he went berserk and told them to push on. Not only that but he would take personal command of operations. Many commanders were angry and flew back to talk to Hitler personally. Hitler did not lose his temper. He sat them down and used his great personal charm to convince them the war was being won, when actually each day any form of victory slipped further from of his grasp.

He could have made a tactical retreat and partitioned the territory already won. However, he had his evil heart set on capturing and making Stalingrad into a symbol of German might. That would have been a good move had the offensive been going to plan but the wheels were falling off so to speak, especially when winter came.  

What if the generals had their way? They may have stopped going forward altogether for no military advantage could be found in pressing on. Their supplies needed to be tripled and that was not about to happen. Troops needed to consolidate the Western front were tied down to favour a place where morale was never very high.
